To all whom it may concern." Be it known that I,"OHRISTIAN J. WOLFE,

a citizen of the United States, residing in Chicago, in the county ofCook and State of Illinois, have invented a new and useful Improvementin Valve-Spring Lifters for Automobile and other Engines, of which thefollowing is a specification.

My invention relates to improvements in valve spring lifters forautomobile and other erfgines.

The object of my invention is to provide an improved construction ofvalve spring lifter capable of being used upon almost every make ofengine, regardless of the room taken up by intake, exhaust, water pipes,etc., which will beof a simple construction, composed of few parts andnot liable to get out of order, in which thelifting of the valve springmay be efiected near the valve and withoutdanger of bendiently,

and held 3 .ing or damaging the valve stem, in which the holder on topof the valve will be stationary and subjected to no screwin or turningaction, by which thelifting o the spring may be done quickly andconvenand whereby when the spring is compressed, the lifter will be firmand rigid in position until released, and which may be quickly andeasily released and removed.

My invention consistsin the means I'em-- I ploy to practicallyaccomplish this object or result as herein shown and described, the samebeing more particularly pointed out in the claim.

struction and operation of my valve spring lifter to be more clearlyunderstood.

My improved valve spring lifter comprises 6, a valve holder arm 7 alifter arm 8 and a thumb nut 9 The stem 6 is furnished at its lowerportion with aplurality of holes 10 for adjustably connecting the lifterarm 8 to the stem by means of a removable cotter or pin 11, which isinserted through the socket 12 of the lifter arm" to adjustably connectthe lifter arm in difierent positions as may be required for operationupon-dif At its upper end the ferent machines. lifter stem 6 isfurnished with double screw threads13, 14 for engagement with the corresponding threads of the thumb nut 9. so as to provide for a quicklifting action. The valve holder 7 has at its lower end a socket 15 forengagement with the valve or its 7O stem, and a horizontally bent arm 16furnished with an integral sleeve 17 through which the lifter stem 6 mayslide under action of the thumb nut 9. The lifter arm 8 is furnished atits free end with a fork 18 adapted to fit astride the valve stem andengagethewasher 5 againstwhich the lower end of the valve spring bears.This fork enables the lifter arm to be laterally removed from the valvestem.

To prevent the lifter arm 8 from slipping off of the lifter'ste'm 6, thestem 6 is proconnected by a pivot pin 20 to the stem 6, and which dogis'adapted to shut into a recess 21 in the, stem 6' to permit the socket12 of the arm 8 to be removed from the stem 6 when desired. The lifterstem with its valve holder and litter arm maybe placed horizontally orinto any position that may be required by a particular valve, The,upright or depending arm 22 of the valve holder 7 enables the valveholder to be inserted within the valve shell as required for engagementwith the valve or upper end of its'stem, l-The fork 18 ofthe.

lifter arm 8 is furnished with a recessed seat 23 to receive the washer5 at the lower end of the valve spring.
